Abstract

There have been so many excellent papers published within the last 15 yr. on the methods of manufacture of lactose that a review of this literature would be repetitious, ttowever, it might be desirable to refer to some of the more important reviews. Webb and Ramsdell (7), Webb and Whittier (8), Whittier (10), and Whittier and Webb (11), have published ex- cellent reviews of the subject. Those by Hun- ziker (5), Kastens and Baldauski (6), and Weisberg (9) should also be included. These papers have been very helpful to the dairy industry. Those from the Bureau of Dairy Industry (7, 10), published during World War II, undoubtedly were responsible for elimi- nating a considerable amount of confusion, as well as saving much time and product, when the production of penicillin caused an increase of more than 200% in the production of lactose within a 3-yr. period.
